Scientific paper

The Voigt function H(a,v) influences the absorption coefficient of the centre and of the wing of a Fraunhofer line differently. The absorption coefficient of the line centre is K(0) ≡ N/ΔλD, and the one of the far wings is K(v) ≡ Nγ. Here N is the concentration of absorbing atoms, ΔλD is the Doppler width, γ is the damping-broadening constant, sharply increasing downward into the photosphere. Due to this, the effective depths of formation of far wings of strong lines are larger than those of weak lines having the same atomic parameters.
